CURTAIN ROD Filed Nov. 6, 1931- INVE OR m NT Patented Apr. 18, 1933@UNITED STATES ISIDOR WEINBERG, OF BROOKLYN, NEW YORK CURTAIN nonApplication led November 6, 1931. Serial No. 573,416.

This invention relates to improvements in curtain fixtures particularlyin fixtures in which the left and right hand parts of a curtainsuspended from the iixture by means of slides or runners, are drawntogether or moved apart, by the operation of a pull cord, and it is theprincipal object of my invention to provide a fixture the telescopingmembers of which carry master slides attached to the pull cord which atall times are centrally located to said members which are substantiallyU-shaped in cross-section and have a rounded apex while the lower endsof the U-shanks are inwardly and upwardly bent 15 to form guides inwhich the members are guided during their telescoping displacement toone another.

Another object of my invention is the provision of double duty bracketsat the outerv '-20 ends of the end members of the lixture to allow theattachment of the fixture by one part of the double duty bracket eitherbetween the inner oppositely disposedfaces of a'window sash or the like,or to permit the attachment of the fixture by means of the other part ofsaid double duty bracket to the side faces of a window sash or the like.

Still another object of my invention is the provision of a curtainfixture the pull cord of which is guided over suitablyarranged `innersheaves in such a manner as to allow the pulling apart of the curtainparts by a pull at one end of the cord or the drawing together of theparts of the curtain by a pull at the other cord end.

A further object of my invention is the provision of a plurality ofslides or runners from which the parts of a curtain are suspendedincluding centrally located master slides adapted to be pulled apart ordrawn together on the central or main member by a pull on the cord andsliding on a seat formed by the inwardly and upwardly bent ends of thefixture members. A

the provision of a curtain fixture the draw or pull cord of which isreentrantly guided over sheaves and secured intermediate its ends to thecentrally located slides' for the curtain, and a ixture which iscomparatively simple and inexpensive in construction, yet durable andhighly eiicient in operation.

Other objects and advantages vof my invention will become more fullyknown as the description thereot1 proceeds, and will then bespecifically deined in the appended claims.

As illustrated, the curtain rod or fixture according to my inventionconsists of a central or main section 10 and two sections 11 and 12telesooping endwse into said main section.

Each section consists of a body part substantially U-shaped in crosssection having a rounded apex and parallel downwardly directed spacedshanks the lower ends of which are inwardly and upwardly bent, asindicated at 13 and 14, the bends of the main section forming a guidefor the bends of the end sections vslidably held therein during thetelescoping operation and forming a seat for the upper bar or head 15 ofthe 'slideslf` and master slides 16,'16Q` having each a web 90 17connecting the head to the foot of the slides 16 and master slides 16,16', bent angularly to form a depending member 18 perforated at 19 toallow the passage of the fastening or suspending means of the curtain.

The apex of member 12 is slotted, as at 20, to permit the telescoping ofmember 12 into the main section.

The outer ends of the end sections 11 and 12 are equipped with doubleduty brackets. one part of each bracket composed of a plate 23 and endvplate 24 angulary disposed thereto and perforated, as at 25, tolallowthe,.passage of the fastening means by which the vfixture is to besecured to the inner faces 'of a window frame, while bracket23 integralwith plate 24 and angularly disposed thereto has perforation 26 to allowthe passage of fastening means securing the bracket to theK end memA pber 12, and perforation 21 fro'mwhich the outer ends of the curtain aresuspended- Integrally formedv with plateA 24 and angul'arlydisposedthereto is the other part ofthe double"'duty'bracket composed-ofa substantially U-shaped body part or plate 27 connected by vmeans of aweb 28 to plate 23 and having the upper and lower ends of the U-v shanksangularly bent to form upper and lower lianges 28, 29, provided Wit-hopenings 36, 31', allowing the passage ofthe fastening means to securethe bracket vmember 27'to the-outer faces of a window-frame.

A sheave or small pulleyfwheel 32 isfrotatably mounted von a pin 33 nearthe outer end of the right handsection between the walls of member 11and one end of a pull cord 34 is guided-'over the sheave and has securedthereto master slide 16 by means 'of a screw 35. The cord 34 is thenguided Vover a sheave 36 secured by means of a pin 37 to al U-.plate oryoke 3S attached to the apex of member 10 by means of screw 22. f

The cord is then reentrantly guided over a pulleyor sheave 39 on pin 40near the inner 'f enfd of the left hand end section of the rod and fromthis sheave cord 34 is guided over a sheave 41 on pin 42 near theouter'end'of the left'hand'se'ction between'the vwalls of member 12.From sheave 41 cord 34 is guid- -f ed over a small roller 43 on pin 44in a member 45 secured in member 12. At a distance from roller v43 vcord34 vis attached by means of screw 44 to master slide 16 and finallyguided over a pulley or sheave 46 on pin 47 inward of and somewhat belowsheave V32 and has its end 48 suspended for the attachment of a suitableweight. A similar weight is attached to end 34 of the cord.

, InY operation, the fixture is adjusted to its 5 proper length by thetelescopic adjustment of in plate' 24er by means .of screws or the like`passed through the openings 30, 31, of bracket member 27, if the fixtureis to be attached to the front face of a window' sash or the like. lnadjusting the fixture to a given length, the end members should each belengthened or shortened equally relative to the main member. lt will beapparent, that by such adjustment, the master slides governing themovements of the curtain, will at all times be centrally located 'on therod, due to the prescribed arrangement of sheaves, provided by thepresent invention.

The curtain .is/.suspended from -the slides 16 and master slides 16,16', by hooks, pins, or the like, passed through the openings 19. 1fVnew -a pull-v is exerted-011 end 34 of the pull cord, the master slides16, 16', from which the inner ends of the curtain are suspended willdistance the ends of the curtain to any desired degreeto provide anopening while a pullon end 48 will approachthe curtain ends towards Vthecenter so as lto overlap and close the curtain and closethe opening. Y.j Y 4 lt will be understood that I have described and shown'thepreferred form of my device only as one example ofthe many possible waysto practicallyv construct the same, and that l may make such changes inthe general arrangement thereof and inthe construction of its minordetails as come within the scope ofthe appended' claims withoutdeparture from the-'spiritof my invention and the prinf ciplesinvo-lved. f Y l -iHavin'g thus described my invention, what I claim asnew and desire to secure by Letters Patent is: n Y;
